Authorities in South Carolina are currently investigating the cause of a puzzling boom that startled residents and caused homes to shake in multiple cities.

However, officials have stated that they do not believe the incident was caused by an earthquake, UPI reported.

Reports of a loud noise emerged on Tuesday morning around 8:40 a.m. from residents in the Lowcountry area of the state. One resident in Mount Pleasant managed to capture the sound on a doorbell camera.

The South Carolina Emergency Management Division is actively investigating the source of the boom. While previous similar incidents have been attributed to earthquakes, officials have stated that they do not believe that to be the case this time.

In a tweet, the emergency management officials stated, “We have no reports of any earthquakes at this time. We’re working to determine the source,” in response to numerous inquiries about the loud boom and rumble in the Charleston area earlier that morning.

The U.S. Geological Survey confirmed that there was no seismic activity detected, and NASA officials clarified that no spacecraft were scheduled to reenter the atmosphere at the time of the sound.

Some residents speculated that the boom might have been the result of a military training exercise announced earlier by the U.S. Coast Guard to be conducted north of Charleston, as reported by UPI.

However, a spokesperson for the Coast Guard stated that they were unable to establish a connection between the exercise and the boom heard on Tuesday.
